Golf MK2 16V Throttle Body

thingiverse

The throttle body on a Golf MK2 16V is designed to regulate airflow into the engine's intake manifold, playing a crucial role in determining how much air and fuel are pumped into the cylinders. It serves as an essential component within the vehicle's engine management system, acting as a critical interface between the engine's computer and the driver's input through the accelerator pedal. The throttle body itself consists of a butterfly valve attached to a shaft that pivots when the pedal is pressed, thereby controlling airflow and consequently influencing the engine's performance characteristics such as power output and fuel efficiency.
